The most recent Google Earth imagery update included some images of Pyongyang dated April 22 and April 23, 2017. It’s a pity they weren’t from a week earlier as North Korea celebrated its 105th anniversary on April 15 with a spectacular march past. There was another march for Army Day on April 25th.

We also came across a story that highlights the dangers of trying to interpret satellite imagery without sufficient background information. There was a story that was published by a number of media outlets that said that North Korea appeared to be building artificial islands with military installations on them. A parallel was drawn with China’s island building efforts in the South China Sea. However, a quick look at the locations mentioned in the story reveals that the islands in question are not artificial. Then the website 38 North published this article, essentially debunking the entire story. It turns out the islands and related construction are just part of a land reclamation project, not unlike many others along North Korea’s coasts. We can see it being constructed starting in 2011 using Google Earth’s Landsat/Sentinel-2 mosaics:

Not far to the west there is a similar wall that has been there since at least 1984 (the oldest available imagery). Below we show the extent of land reclamation behind the sea wall:

Another interesting story from 38 North is this one, where they spotted North Koreans apparently playing volley ball near the Punggye-ri nuclear test site. Unfortunately, that imagery has not made it into Google Earth.
